    Description / Table of Contents: Summary 1. In aqueous phosphate buffer diacetyl tartaric acid monoglyceride is hydrolyzed to glyceride and tartaric acid. 2. Orally administered14C-labeled emulsifier to rats is absorbed to 26–31% of the activity given. 3. 21–20% are oxidized to14CO2, 8–13% are excreted in the urine, 2% are retained in the carcass.
    Notes: Zusammenfassung 1. Die vorliegende Substanz wird in geringem Umfang, maximal zu 10–20%, im wäßrigen Medium gespalten. 2. Im Organismus der Ratte wird rd. 1/3 der14C-Aktivität der Substanz resorbiert. 3. Die Ausscheidung der14C-Aktivität erfolgt zu 12–20% via Lunge, zu 8–13 % via Niere, während der im Körper verbleibende Anteil nur 2% ausmacht.

    Description / Table of Contents: Abstract 5-Carboxyl-substituted 3.3-diphenyl-2-amino-1-pyrrolines are conveniently prepared by cycloaddition of α-acetaminoacrylic ester to diphenylacetonitrile. An alternative route, starting with the 4.4-diphenyl-4-cyano-2-bromobutyric acid derivatives1 b or1 d, results in poor yields owing to elimination of HBr during amination. Several amides of 3.3-diphenyl-2-aminopyrroline-5-carboxylic acid were prepared, including the β-carbamidinoethylamide (rac. diphenylnoformicin). Reduction of the ethyl ester2 f yields 3.3-diphenyl-2-amino-5-hydroxymethyl-1-pyrroline (3).
    Notes: Zusammenfassung 5-Carboxylsubstituierte 3,3-Diphenyl-2-amino-1-pyrroline werden vorteilhaft durch Cycloaddition von α-Acetaminoacrylester an Diphenylacetonitril hergestellt. Ein zweiter Syntheseweg, ausgehend von den 4,4-Diphenyl-4-cyan-2-brombuttersäurederivaten1 b oder1 d, verläuft wegen der HBr-Eliminierung während der Aminierung mit schlechten Ausbeuten. Es werden einige Amide der 3,3-Diphenyl-2-aminopyrrolin-5-carbonsäure (2 c), darunter das β-Carbamidinoäthylamid (rac. Diphenylnoformicin) (2 h) hergestellt. Die Reduktion des Äthylesters2 f führt zum 3,3-Diphenyl-2-amino-5-hydroxymethyl-1-pyrrolin (3).

    Description / Table of Contents: Zusammenfassung Die Acylierung von 2-Amino-3.3-diphenyl-5-methyl-1-pyrrolin (1) und 2-Amino-3.3-diphenyl-1-pyrrolin (2) erfolgt in den hier untersuchten Fällen am N-2-(exo)-Stickstoff. Die Umsetzung der cyclischen Amidine1 und2 mit BrCN gibt jedoch neben den N-2-(exo)-auch die N-1-(endo)-Cyanamidine. Diese werden in die entsprechenden Carbamoyl- und Thiocarbamoylamidine umgewandelt.
    Notes: Abstract Acylations of 2-amino-3.3-diphenyl-5-methyl-1-pyrroline (1) and 2-amino-3.3-diphenyl-1-pyrroline (2) occur at the N-2-(exo)-nitrogen. However, reaction of1 and2 with BrCN yields not only the N-2-(exo)-cyanoamidines but also the N-1-(endo)-isomers. Either is converted into the corresponding carbamoyl and thiocarbamoyl amidines.

    Description / Table of Contents: Zusammenfassung Aus 2-Amino-1-pyrrolinen können durch bekannte Reaktionen stabile Carbamidinoderivate dargestellt werden. Die Addition von Bisbenzhydrylcarbodiimid an 2-Amino-1-pyrroline, gefolgt von saurer Abspaltung der Benzhydrylreste, stellt eine neue vorteilhafte Methode zur Herstellung der nor-Derivate dieser Verbindungsklasse (Tab. 2) vor. Einheitliche N2-Alkyl-und Arylsulfonylderivate dieser Reihe erhält man mit den 1-(N2-Sulfonylcarbamidino)-3.5-dimethylpyrazolen.
    Notes: Abstract Stable carbamidine derivatives of 2-amino-1-pyrrolines have been prepared using known reactions. The addition of bis-benzhydrylcarbodiimide to 2-amino-1-pyrrolines followed by acid cleavage of the benzhydryl moieties provides an improved method for the preparation of nor-derivatives of this class of compounds (Table 2). N2-Alkyl-and arylsulfonyl derivatives of this series have been selectively obtained from 1_(N2-sulfonylcarbamidino)-3.5-dimethylpyrazoles.

    Notes: Abstract Any conformal or projective structure on a manifold ℳ defines a natural boundary ∂ℳ. For Minkowski space these coincide with null infinity as defined by Penrose and projective infinity as defined by Eardley and Sachs, respectively.
